1. A method for monitoring a physical downlink control channel (PDCCH) by a user equipment (UE), the method comprising:
reporting capability information indicating a first set of one or more pairs and a second set of one or more tuples, wherein:
each pair of the first set comprises a first value indicating a number of serving cells configured for per-slot monitoring and a second value indicating a number of serving cells configured for per-span monitoring across cell groups; and
each tuple of the second set comprises a first value indicating a number of serving cells configured for per-slot monitoring in a master cell group (MCG), a second value indicating a number of serving cells configured for per-slot monitoring in a secondary cell group (SCG), a third value indicating a number of serving cells configured for per-span monitoring in the MCG, and a fourth value indicating a number of serving cells configured for per-span monitoring in the SCG;
receiving, in response to the capability information, a first pair of values for the MCG and a second pair of values for the SCG, wherein a first value in each of the first and second pairs of values is a maximum number of serving cells configured for per-slot monitoring, and a second value in each of the first and second pairs of values is a maximum number of serving cells configured for per-span monitoring;
determining, for each of the MCG and the SCG, a monitored candidate limit per slot based on the first value in each of the first and second pairs of values; and
determining, for each of the MCG and the SCG, a monitored candidate limit per span based on the second value in each of the first and second pairs of values.
